Basically he's a bodyguard/janitor/lab assistant for one of my other characters, he was modified with cybernetics through most of his body giving him even more impressive strength than he originally had, though he's quite slow due to these mechanical parts.
He has a bladed claw on one hand along with his signature weapon, a flamethrower. The flamethrower is also equipped with a beartrap-like jaw that can be fired off on a chain to reel in enemies from long distance to compensate for his sluggishness.
He's basically mute, his gas mask makes him speak at a frequency that coincidently only his master can hear. The only indications of him being around are his metal footsteps and Darth Vade breathing.
My main inspiration for him was the Cremators, a cut enemy from Half Life 2.
